Lot size & risk calculator

Define your risk per trade and stop loss distance to get a suggested lot size.

Account balance

Risk per trade (%)

Stop loss distance (pips)

Pip value per 1.00 lot (account currency)

Risk amount –

Suggested lot size –

Risk per pip –

Calculations assume the pip value you enter is for a standard 1.00 lot. Always double-check position size on your broker platform before placing a trade.

Risk / Reward & R-multiple calculator

Use your entry, stop loss and take profit prices to see the R-multiple and risk/reward of your trade idea.

Entry price

Stop loss price

Take profit price

Trade direction –

Stop distance –

Target distance –

R-multiple (target) –

Risk / Reward ratio –

This tool uses raw price distances (no spread, commissions or pip conversions). Make sure your stop and target are on the correct side of price for the trade direction.

Drawdown & recovery calculator

See your drawdown and how much percentage return you need to recover to your peak or a new target balance.

Peak balance (or starting equity)

Current balance

Target balance (optional)

Drawdown amount –

Drawdown percentage –

Required gain to recover to peak –

Gain to reach target (if set) –

Recovery % is calculated from your current balance. Large drawdowns always require disproportionately larger returns to get back to the same equity high.

Prop firm rules helper

Use your account size and prop firm limits to see your daily loss cap and how many full-risk trades fit inside the rules.

Account size

Max daily loss (%)

Max overall loss (%)

Risk per trade (%)

Daily loss limit (amount) –

Overall loss limit (amount) –

Max full-risk trades per day –

Max full-risk losses before overall limit –

Calculations are based on your inputs only. Always check the exact wording of your prop firm's rules (daily loss, equity vs. balance, trailing vs. static) before trading.

Breakeven price calculator

Use your entry, trading costs and trade direction to see the real breakeven price of your position.

Trade direction

Entry price

Total trading cost (pips)

Pip size (price units)

Cost in price units –

Pips needed to breakeven –

Breakeven price –

This tool assumes your total cost is entered in pips and converted using the pip size. Always confirm with your broker's platform before placing or managing trades.

Pip & value converter

Convert between pips and monetary value using your lot size and pip value per 1.00 lot.

Pips (for pips → money)

Amount (for money → pips)

Pip value per 1.00 lot (account currency)

Lot size

Value for entered pips –

Pips for entered amount –

Value per pip (this position) –

Value per pip is calculated as: pip value per 1.00 lot × lot size. Use the sign of your trade (profit or loss) when applying these numbers to real positions.

Win rate & R needed calculator

See the break-even win rate for your R-multiple, the R needed for your win rate, and the expectancy of your system in R per trade.

Win rate (%)

Reward-to-risk (R multiple)

Target expectancy per trade (R, optional)

Expectancy (current, R/trade) –

Break-even win rate for this R –

Break-even R for this win rate –

Win rate needed for target R expectancy –

R multiple needed for target expectancy –

System edge –

Formulas assume average loss = 1 R. Expectancy (per trade) = WinRate × R − (1 − WinRate). Break-even occurs when expectancy = 0.

Max trades per day based on risk

Use your account size, daily loss limit and risk per trade to see how many full-risk trades fit inside your rules.

Account balance

Daily loss limit (%)

Risk per trade (%)

Safety buffer (%) for max trades (optional)
